**Chapter 1: Turbulent Takeoff**

As I sat in my wheelchair, my heart racing with anticipation, I couldn't help but feel a mix of excitement and trepidation. I was finally going to visit my grandmother in Tokyo, Japan, a trip I had been dreaming of for years. My grandmother, or "Obachan" as I affectionately called her, had always been my rock, my confidante, and my guiding light. I had been born with severe autism spectrum disorder, which made everyday interactions a challenge, and my blindness in both eyes only added to the complexity of my daily life. But despite these obstacles, I had learned to navigate the world in my own way, and I was determined to make the most of this trip. As I made my way to the gate, my senses were already on high alert. The fluorescent lights overhead seemed to hum at a deafening pitch, and the murmur of the crowd was a cacophony of sound that threatened to overwhelm me. I took a deep breath and focused on the gentle hum of my own breathing, trying to calm my frazzled nerves. As I boarded the plane, I was relieved to see that I would be sitting in a specialized sensory-friendly seat in first class. The airline had assured me that this seat would be tailored to my specific needs, with adjustable lighting and noise-cancelling headphones to help me cope with the sensory overload that often came with flying. I settled into my seat, feeling a sense of comfort and security wash over me. The flight attendant, a kind-faced woman with a warm smile, came over to greet me. "Welcome aboard, Nick," she said, her voice soft and gentle. "Is there anything I can get for you before we take off?" I smiled back at her, feeling a sense of gratitude for her kindness. "Just a glass of water, please," I replied, my voice barely above a whisper. As the plane began to taxi down the runway, I felt a sense of excitement build inside me. I was really doing this – I was going to Tokyo! But just as the plane was about to take off, the flight attendant returned to my seat, looking apologetic. "I'm so sorry, Nick, but I have some bad news," she said, her voice tinged with regret. "It seems that Prince Hange, a... ah... distinguished passenger, has booked the entire first class flight seat in advance for his business trip to Tokyo. We're going to have to move you to a different seat." My heart sank, and I felt a wave of agitation wash over me. What? They couldn't be serious! This was my seat, the one place on the plane where I felt safe and comfortable. And besides, I couldn't sit in economy – the thought of being surrounded by other passengers, with their noise and their chaos, was too much to bear. The flight attendant seemed to sense my distress, and she reached out to put a gentle hand on my arm. "I'm terrible sorry, Nick," she said, her voice filled with empathy. "But there's no room in first class. We'll do our best to find you a seat that's comfortable, but... " I felt my anxiety spike, and I took a deep breath, trying to calm myself down. But it was too late – I was already starting to feel overwhelmed, my senses on high alert as I struggled to process this sudden change. And then, just as I was starting to feel like things couldn't get any worse, I heard a voice behind me – a low, smooth voice that seemed to command attention. "Wait," the voice said. "What's going on here?" I turned my head, trying to locate the speaker, and that's when I saw him – Prince Hange, the infamous leader of the Yakuza and the Elder Dragon King. I had heard stories about him, of course, but I never thought I'd meet him in person. And now, it seemed, he was standing right behind me, his eyes fixed intently on me. What did he want? And what would happen next?
